  • Apache Ant Best Practices
    08_Lee_ch05.qxd 5/3/06 5:12 PM Page 81 C HAPTER 5 Apache Ant Best Practices This chapter looks in more detail at some best practices for using Ant on real projects. First I describe the use of property files to enable configuration of the build process depending on a user’s role and requirements. I then describe how best to integrate Ant with IBM Rational ClearCase. Finally, I look at some general best practices for supporting the build process on large projects. Aims of This Chapter Apache Ant is a powerful build tool with significant built-in capabilities. However, a few capabil- ities and best practices stand out; they are described here. After reading this chapter, you will be able to • Understand what Ant property files are and how they can be used to make build scripts more maintainable. • Understand how to use Ant’s capabilities to better integrate with IBM Rational ClearCase. • Implement Ant build files that support reuse and maintainability on large projects. This chapter assumes that you are familiar with the basic concepts of Apache Ant that were discussed in Chapter 4, “Defining Your Build and Release Scripts.” Property Files From the perspective of Chapter 4, an Ant build.xml file is a single centralized build file that defines a repeatable process for bringing together an application, usually producing some form of 81 08_Lee_ch05.qxd 5/3/06 5:12 PM Page 82 82 Chapter 5 Apache Ant Best Practices executable output. Although a single build.xml file can be enough to drive the build process, in practice it can quickly become large and unwieldy.

  • Build Notifications in Agile Environments
    University of Calgary PRISM: University of Calgary's Digital Repository Science Science Research & Publications 2008-01-14 Build Notifications in Agile Environments Ablett, Ruth; Maurer, Frank; Sharlin, Ehud; Denzinger, Joerg; Schock, Craig http://hdl.handle.net/1880/45854 unknown Downloaded from PRISM: https://prism.ucalgary.ca Build Notifications in Agile Environments Abstract. In an agile software development environment, developers write code that should work together to fulfill the wishes of the customer. Continuous integration (CI) ensures that code from different individuals integrates properly. CI compiles the entire codebase, deploys and tests it with each change. CI alerts developers of any problems as errors can be fixed more easily if caught earlier in the process. This paper compares the effectiveness of different types of mechanisms for notifying developers to a successful or unsuccessful build. Two different quantitative and qualitative user studies were performed testing the effectiveness of three types of notification devices – one virtual e-mail based mechanism, one using ambient lava lamps, and one robotic device. The results show that most developers preferred an easily visible but unobtrusive ambient device combined with an e-mail describing the problem in more detail. Keywords: Agile methods, information awareness, ambient display, continuous integration 1 Introduction Agile methods [1] are becoming popular in the software industry. In agile software development projects, there may be anywhere from one to hundreds of developers working concurrently on the code base, so it is imperative that all software written by each developer integrates properly into the entire project. To this end, most agile teams adopt Continuous Integration (CI).

  • Continuous Integration in LATEX Marco Antonio Gómez-Martín and Pedro Pablo Gómez-Martín
    The PracTEX Journal, 2010, No. 1 Article revision 2010/01/01 Continuous Integration in LATEX Marco Antonio Gómez-Martín and Pedro Pablo Gómez-Martín Email [email protected], [email protected] Abstract Have you ever co-written a paper using LATEX together with some version control system such as SVN? Have you ever updated your local copy and the compilation has become broken due to a previous bad commit? Con- tinuous integration avoids this problem using an auxiliary server that constantly checks the sanity of the repository, compiling the LATEX doc- uments after each commit, and notifying authors of possible problems. This paper describes how to configure this environment. Although the configuration effort is detailed, it is done only once and provides many benefits. In addition to doing compilation tests, all authors can be auto- matically informed by e-mail when a new version is committed, and the current .pdf version can be made available to third parties on the Web. 1 Introduction Many of the documents that we write using LATEX are created not by just one author but two or more. In fact, our analysis performed over the database of the DBLP computer science bibliography1 reveals that the average number of authors of books, journal articles and articles in proceedings written until February, 2004 was 2.26 (see table1). This justifies the use of some kind of version control system, such as CVS (2) or Subversion (4) (also known as SVN) for collaborative writing of LATEX documents. As the use of SVN has spread over the LATEX community, different packages have appeared that allow documents to incorporate references to the properties of the last revision (10).
